Internet of things-based intelligent household system

The invention discloses an internet of things-based intelligent household system, which comprises a main machine circuit and an inferior machine circuit, wherein output ends of a main machine circuit clock module, an input module and a sensing module are electrically connected onto a first control module, input ends of an alarming module and a liquid crystal display (LCD) display module are electrically connected onto the first control module, a first radio frequency receiving-transmitting module is bi-directionally communicated with the first control module, and the information receiving-transmitting module is electrically connected with the first control module through a reference standard (RS)232 serial port; a second control module receives a signal transmitted by a second radio frequency receiving-transmitting module from the main machine circuit and controls a relay control module to work according to the signal; and the main machine circuit and the inferior machine circuit are wirelessly communicated with each other through the first radio frequency receiving-transmitting module and the second radio frequency receiving-transmitting module. Therefore, the house environment can be remotely controlled.
